Policy, plan, programme or projects | Interactions resulting in cumulative impacts National (example) Transport 21 Programme | Potential in-combination impacts may arise where new or upgraded transport corridors are constructed in line with new or upgraded transmission infrastructure. Impacts may include the following: — Habitat loss and disturbance. All terrestrial based designated sites may be affected, depending on where infrastructure and transmission lines are located/routed. — Alterations to local hydrology and effect on adjacent habitats. Groundwater dependant habitats such as fens, turloughs and bogs are most likely to be affected. — Sediment pollution and associated hydrological impacts where surface water dependant species and habitats are affected. Salmon, lamprey, white clawed crayfish and freshwater pearl mussel may potentially be affected. — Contamination of surface and groundwater with pollutants (e.g. fuels, lubricants, concrete) during construction. Salmon, lamprey, white clawed crayfish and freshwater pearl mussel may potentially be affected. — Disturbance of species during construction and maintenance activities. Species that may be affected include nesting and overwintering birds in coastal and freshwater SPAs; otters and kingfishers, where development occurs adjacent to or crossing watercourses; bats, where development affects woodlands, hedgerows or roosting sites. — Risk of bird strike where overhead transmission cables are installed near SPAs or across bird flight lines. Regional (example) Regional waste management plans | Potential in-combination impacts may arise where new waste infrastructure and new transmission infrastructure occur together within or in close proximity to a designated site. Likely significant impacts are as previously outlined. County (example) County and town development plans | Potential in-combination impacts may arise where there is a requirement to provide for new infrastructure through implementation of county and town development plans. Provision of related transmission infrastructure may result in likely significant impacts as previously described. Projects Offshore energy generation projects | In-combination impacts may arise at the interface between offshore and on shore infrastructure. Impacts that may occur include: — Habitat loss and disturbance. All terrestrial based designated sites may be affected, depending on where infrastructure and transmission lines are located/routed. Loss of habitats may also occur in the littoral and coastal zones. Habitat loss will be grater where underground cables are installed. — Sediment pollution and associated hydrological impacts where surface water dependant species and habitats are affected. Salmon, lamprey, white clawed crayfish and freshwater pearl mussel may potentially be affected. — Contamination of surface and groundwater with pollutants (e.g. fuels, lubricants, concrete) during construction. Salmon, lamprey, white clawed crayfish and freshwater pearl mussel may potentially be affected. — Disturbance of species during construction and maintenance activities. Species that may be affected include nesting and overwintering birds in coastal and freshwater SPAs; marine mammals, where interconnection between offshore and onshore infrastructure occurs; otters and kingfishers, where development occurs adjacent to or crossing watercourses; bats, where development affects woodlands, hedgerows or roosting sites.
